Last week I mentioned these. The top one called “Harvest of Death” (!) is supposed to be a group of dead Confederate soldiers; the one with trees in the background Northerners. But if you look closely at the detail (flipped & zoomed) in the third frame, you realize it’s really the same group of soldiers (see esp. the one with crossed legs and a rock behind his head).

O’Sullivan worked with Matthew Brady’s protege Alexander Gardner, whose name also appears on the photos.
